An Act relative to domestic abuse protection, "Katherine's Law"

This bill, "Katherine's Law," creates specific protections for domestic abuse victims and their children across multiple systems. It extends tax filing deadlines for victims who shared a joint return with an abuser, expands MassHealth coverage for 12 months regardless of income for victims and their children, and changes custody rules to create a rebuttable presumption against awarding custody to abusive parents. The law also modifies housing petitions and mandates that courts consider abuse determinations when reviewing child custody cases. These provisions directly affect individuals and minors who have been determined to have suffered abuse from a family or household member, as defined under Chapter 209A.
